future. In the administration of the na- 

 tional forests there is being developed 

 gradually what I believe to be a truly scien- 

 tifie system for attaining a concrete eco- 

 nomic end, a system of controlling certain 

 correlated industries with a single purpose 

 in view — the maximum of the welfare of 

 the nation as a whole. In spite of many 

 mistakes which we have undoubtedly made 

 and which we have attempted to correct as 

 we went along, in spite of the lack of prac- 

 tise and experience in solving the problems 

 at hand, this new policy, it seems to me, has 

 already proved entirely safe and workable. 



On the occasion of the visit of the associa- 

 tion to Stanford University on Wednesday, 

 August 4, Professor Harris J. Ryan wiU give 

 demonstrations with high potential electric 

 currents in the new laboratory which has been 

 equipped for high potential experimentation.

A JOINT session of the American Mathe- 

 matical Society, the American Astronomical 

 Society and Section A of the American Asso- 

 ciation for the Advancement of Science will 

 be held on Tuesday, August 3, at the Univer- 

 sity of California, for the presentation of two

 omical research will make an excursion to the 

 Lick Observatory, Mount Hamilton, near San 

 Jose. The director of the Mount Wilson Solar 

 Observatory, near Pasadena, extends a cordial 

 invitation to men of science interested in 

 astronomical and physical research to visit the 

 observatory either before or after the San 

 Prancisco meeting of the association. 



Physicists are invited to attend a joint ses- 

 sion for mathematics, astronomy and physics 

 on Tuesday, August 3. One session of the 

 meetings devoted to physics will give consid- 

 eration to recent speetroscopical investigations.
